The objective of this research is to promote real – life mathematical connection ability in exponential and logarithmic functions. The population used for this research was two classrooms of grade 10 students, semester 2 in the 2020 academic year of Suksanari School, with 77 students. The researcher used the cluster random sampling method to select a sample of one classroom of 31 students. The research instruments include pre – post tests for real – life mathematical connection ability and eight "Flipped Classroom" lesson plans based on Donald and Maki's approach (consist of six steps; Revisit, Real World, Real Model, Classroom Model, Mathematical Model, and Conclusion.) The results of the instrument quality test showed that the reliability of the pretest and posttest for real – life mathematical connection ability from five experts with the Alpha Cronbach coefficient was 0.84, a difficulty score of 0.36 to 0.68, a discrimination score of 0.23 to 0.50, and validity score of 0.95. The statistics used to analyze the data were reliability, content validity, and relative gain score. Furthermore, we use content analysis to analyze the written solution's completeness for showing their mathematical connection. The results revealed that all students had improved the mathematical connection ability to real – life. The progress of real – life mathematical connections can be observed from the students' performance in each lesson plan. Students can understand the situation better and answer the key questions clearer in the step for Real World, Real Model, and Classroom Model of Donald and Maki's approach.

Keywords: Donald and Maki’s Approach, Exponential and Logarithmic Functions, Flipped Classroom, Mathematical Connection Ability to Real – Life.
